I took Latin this year and regret it immensely. I've wasted a lot of time learning the specifics of a dead language. I'll be taking Spanish next year, which I'll be able to apply in my life because I live in the US Midwest. Any recommendations for immersion?
I was writing a longer comment but lost it due to losing wifi signal and subsequently restarting Chrome. Anyway, the gist of it: Of those languages, I found Latin to be the most valuable to my linguistic insight. Nearly all West-European languages have their roots in it, including English. I didn't like having Latin because it was a language, not because it was Latin. I mean, I have translated parts of Caesar's De Bello Gallico and Pliny the Younger's letters to his uncle, explaining the Pompeii eruption. Closer to classical history you cannot get. For immersion, I would recommend finding a forum or site on a topic you're interested in, in the language that you want to learn. You could also try reading the Spanish news.
